I have a 2005 Murano with this feature. Yesterday was the first really cold day here in Toronto and on my way home from work this warning light came up along with a scary loud alarm. Scared the S*!#t out of me. I pulled over and found the manual and read that it was my tire pressure alarm. I checked my psi and it had dropped to 27 because of the cold. I topped up the air in the tires but the light did not go away. This morning I figured it would be gone but it wasn't. I checked the display and it now still said I had a flat tire but all my psi readings were over 31. I called nissan when I got to work and they told me I had to drive for about 10 miles before that light goes out. It did eventually go out but it would have been nice to have read that in the manual. Who's supposed to know that!
